HARRY M. ESSINGTON, OF CAMDEN, NEW JERSEY, ASSIGNOR TO THE ESSING- TON BUTTON-HOLE FINISHING MACHINE COMPANY.

'BUTTON-HOLE-BARRlNG MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 377,931, dated February 14, 1888.

Application filed J one 24, 1886.

To all whom it mag concern:

Be it known that I, HARRY M. EssINGToN, a citizen of the United States, residing inthe city and county of Camden, State of New Jersey, have invented a new and useful Improvement in Machines for Finishing Button-Holes, which improvement is fully set forth in the following specification and accompanying drawings, in whichv Figure 1 represents a partial top or plan view and partial horizontal section of a machine for finishing button-holes embodying my invention. Fig. 2 represents a side elevation of a portion thereof. Fig. 3 represents an end view thereof, partly sectional in line as m, Fig. 2. .Figs. 4 and 5 represent vertical sections of .a detached portion on an enlarged scale. Fig. 6 represents a top view of a detached portion. Fig. 7 represents a view of a portion of Fig. 6, the parts being in different positions. Figs. 8 and 9 are views of the line of stitches as made by the device describedherein. Fig. 10, Sheet 2, represents a perspective view of abutton-hole-finishing machine embodying my invention as seen. from the .side and a little to the rear thereof.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a machine for finishin g buttonholes embodying means for guiding the fabric, leather, &c.,'containingv the button-hole in both transverse and longitudinal directions, so as to form stitches across the unfinished end of the button-hole, and then overstitch the same, as will be hereinafter set forth.

Referring to the drawings, A represents a table, and B the clamp for the fabric, leather, &c., containing thebutton-hole.

A represents an upright piece of metal of the shape of the opening of a button-hole,

' which forms a guide for the button-hole to be finished, which is to be fitted on said piece,

, and thus centered for producing true and uniformwork.

The clamp 13 is pivoted to a longitudinallymovable slide, 0, which is fitted between guides D, which are attached to a transverselyextending slide, E, the latter being fitted between guides F, which are secured to the table A. Projecting laterally from the inner end of the slide 0 is an arm, G, and engaging Serial No. 206,109. (No model.)

the slide 0 is 'a lifting cam or abutment, Q,

with which is adapted to engage the nose of a bar, B, which is pivoted at the end opposite to its nose to a bar, S, which extends horizontally and transversely on the table A, and is pivoted thereto, said bar R having a lateral projection or pin, a, which serves to hold the bar J in elevated position. To said bar R, intermediate of its ends, is pivoted'a vertical bar, T, whose upper end is pivoted to the support U. I

I Y represents a horizontal sliding bar,which is sustained adjacent'to the support U, and has a shoulder, W, which is adapted to engage with the walls of a recess or-notch, X, formed in the periphery of the clutch-pulley Y, which is fixed to the driving-shaft A of the machine. The bar V has at its outer end an arm which loosely enters a groove in the hub of the driving-pulley Z, which latter is loose on the driving-shaftand adapted to be moved to and from the pulley Y, the latter having a table A.

' Motion is impar'tedto the sliding bar G by means of a pivoted lever, K, which is connected at its lower end with said bar, and has its upper end engaged by a cam, L, on'the driving-shaft A. The noses of the pawls F engage with a rack-bar, M, which, is supported on the table A and formed with a nose, N, which is adapted to enter'a notch or recess, P, on the adjacent side of the pivoted bar S. On the side of the bar S is astop, Q, which, when the bar M returns to its normal position by the action of the spring R, is in such position that said bar strikes said stop, the stop being mainly adapted to engage with the end of the lever J and prevent motion thereof.

S represents a bar or lever which is pivoted to the side of the table, and has a notch, T, into which drops a stud or roller, U, on the bar S. The end of the lever S opposite to the bar S is pivoted to a sliding bar, V, which carries an arm, W, the latter being located under the dogs or pawls X, the noses or points whereof engage with a ratchet or rack bar, Y, which is attached to the slide E, so that when said arm WV is moved in one direction by the bar V the pawls are raised clear of the rack -bar, and in the other direction the pawls engage with said rack-bar and impart motion thereto, said pawls being hung on arocking arm, Z, which is operated by an arm, Z and a rockshaft, Z the latter receiving motion from the driving-shaft of the machine in any suitable manner.

To the guides D, which are secured to the slide E and move therewith, are pivoted dogs B, with one of which the lever or arm J is adapted to engage, and with the other an arm or lever, H, is adapted to engage, said arm H being pivoted to the table A and connected with the arm or lever H.

Dogs B are pivoted to the table A and have their inner end beveled and located adjacent to the sides of the slide E, their front ends carrying pins B which are located under the dogs B, springs B being employed for pressing the dogs B" downwardly.

The pivoted arm or bar S has a spring, B, the sliding arm or bar G has a spring, B, and the lever S has a spring, B for restoring said parts to their normal positions or causing the return motions thereof.

The stop B is pivoted to the clutch-pulley Y, and has a pin, B which enters a segmental slot, B in said pulley. A spring, B is employed for returning said stop to its normal position, said spring being suitably secured to the pin B and a proper part of the pulley.

The operation is as follows: The material having the button-hole stitched around the eye and along both sides which is to be finished fiplaced on the guide A and clamped, and

power applied to the driving-shaft, whereby the several parts of the machine are set in motion. The wheel Z, being primarily disengaged from the wheel Y, is moved toward the needle-operating arm by the bar V, so that it is clutched with said wheel Y. An elbow-lever, B, is pivoted to the machine, and, with the treadle-eonneetion B", pivoted to one end of said lever B, operates the said bar V by means of a stud on said bar. As the wheel Z is rotated rapidly and its shoulder C strikes the stop B", the latter yields, and, owing to.the spring B, the wheel Z is prevented from abruptly engaging with the wheel Y. The cam L moves the bar or lever K, thus operating the sliding bar G, and consequently the levers or bars ll J H". The levers J H alternately bear against the dogs B, it being noticed that the slide E has its guide D of one side in contact with the beveled end of the adjacent dog B, as seen in Fig. 4; hence the dog B is lowered and the bar J comes in contact with the dog B, so as to move the latter. As the guide D of the opposite side is not in contact with the dog B, the spring B lowers the dog B and raises the dog B, so that the bar H may move freely under saiddog B without engagement therewith. The slide E is now moved, carrying with it the slide 0 in the transverse direction of the machine, and the button-hole follows said motion. The slide, having made its advance motion, reaches the opposite dog, B, raises it, and causes the dog B to lower. Meanwhile the bar H returns from under the dog B and then again advances, whereby it strikes the dog B and causes the slide E and its superimposed parts to return to the first position; and these operations are repeated until stopped in the automatic manner hereinafter described. The action of the needlein this device is the same as in other and wellknown machines having a merely rising-andfalling motion, and as the cloth is carried backward and forward the thread of the needle is caused toform transverse stitches on the edge of the button hole, as seen in Fig. 8. The pawls F move with the sliding bar G and advance and return over the ratchet or rack bar M, so as to move thelatter the distance of one tooth each motion of said bar G. When the last tooth of said bar is reached, the nose N registers with the notch P, when the spring B forces the lever or bar S so that said nose N and notch P interlock, the stop Q also abutting against the end of the lever J, so as to prevent motion thereof by reason of the straight edge of said stop abutting against the end of the said lever. As the lever J is locked the bar G is also locked, the upper end of the lever or bar K being held from the cam so as not to receive motion therefrom. As the bar S moves, it advances the bar R, and the nose of the latter leaves the abutment Q, and thus drops, whereby the rod or bar J also drops and its lugs H H are in position to engage with opposite sides of the arm G on the slide 0. The bar or lever K continues its oscillations due to the follower M and grooves N, and operates the bar J, whereby its lugs H impart movement in opposite directions to the slide 0, whereby longitudinal motions are imparted to the buttonhole, or at a right angle to the previous ones, With the motion of the bar S just above stated the stud or roller U is placed in line with the notch or recess T, and the lever S is thus permitted to move, whereby the bar V moves outwardly, carrying with it the arm or pin W. This permits the pawls X to lower, and their points then engage with the raek-bar Y, thus imparting forward or transverse motion to the slide E and its superimposed parts, it being noticed that the pawls are operated in opposite directions by the action of the rock-shaft Z connection Z", and arm Z, the said rock -shaft Z receiving motion in connection with the driving shaft of the machine; but as any ordinary mechanism can be employed for this purpose,

and the same not constituting, in itself, any

partof this invention, the same is not shown in the drawings. The button-hole thus receives the finishing stitches, which are over the firstnamed stitches and at a right angle thereto. When the full number of stitches have been made, the treadle is let go, and the wheels Z Y are unclutched and the machine is stopped.

As the lever D is carried back by the sliding bar V, its lower end comes in contact with the heels of the pawls F and raises the teeth thereof clear of the rack-bar M. The lever T is also carried back by the bar V, owing to the stud V thereon. This moves the bar S from the bar M and clears the nose thereof. The spring R then presses against the bar M and returns it to its first position. The stud or roller U also moves from the notch T and rides on the inclined wall thereof, so as to move the lever S, the effect of which is the movement of the pin or arm W in an inward direction, thus raising the pawls X clear of the ratchet or rack bar Y. The bar S also unlocks the lever J, and thus the parts are in theirnormal position, ready for repetition of the movements above stated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
